People are famous for lots of reasons – because they’re beautiful, or funny, or tragic, or talented.

Some even manage it without any of those things.

But with few exceptions – Professor Stephen Hawking, for example – there aren’t many who achieve stardom on the basis of their intellect.

And why should they? Would the world want to be deprived of the cyclical rise-crash-rise-crash life lessons of Kerry Katona? Would we be a better planet if Bruce Willis was known for quoting Nietzsche rather than the Lone Ranger?

Hell, no. And let’s face it, I’d be out of a job if these people suddenly had an attack of the clevers.

Yet every now and then there comes a point where, collectively, Planet Celebrity gets so bonkers-crazy-up-itself that it needs pointing out.

Up to this point most of us can probably have some sympathy for their extraordinary situation in life. It’s a cage I’d never want to live in.

The celebs I’ve seen up close have struck me as the kind of people that have a deep need inside them which fame, money, and attention almost – but never quite - fulfills.

I tend to want to pat them on the arm and tell them they’d be happier being able to take the bus. But then someone like Lenny Henry comes along and sympathy evaporates.

On Tuesday the BBC finally broadcast – having long delayed it – a Panorama investigation into what happens with charity money.

It discovered that Comic Relief had invested millions in the alcohol, tobacco and arms industries and its wage bill had doubled in just four years. New accounting procedures introduced in 2009 also help obscure where the charity invests the money raised.

So that’s reasonable scrutiny of a charity run by people who should know better somehow snatching food from the mouths of babes all over the world.

Thanks, Lenny. That’s the first time you’ve made me laugh in years.

One, good journalism has made a massive charity announce a review of its own investments.

Two, if it leads to Comic Relief NOT giving money to arms manufacturers, tobacco companies which target children, and alcohol firms whose products contribute to misery worldwide, that’s a GOOD THING.

These investments are a tiny portion of the total, Comic Relief obviously does amazing stuff , and it makes sense to turn a profit from donations so the profit pays for staff costs and the donations go to good use.

But wake up and smell the cordite, Lenny. Investing in bullets and cigs is not what you should be about, and in your shoes I’d be feeling both embarrassed and grateful someone had pointed it out.

Celebrities, like it or not, are role models. There’s nothing wrong with expressing an opinion, raising money, a spot of activism if that’s your thing.
